Objective To evaluate and compare the 3 common inspection techniques for acute atlantoaxial trauma:tomosynthesis(DTS),digital radiology(DR) and computed tomography(CT).Methods The imaging data from March 2013 through December 2017 were retrieved from the Picture Archiving and Communication Systems(PACS) of The First Affiliated Hospital of Chongqing Medical University concerning the patients with acute atlantoaxial trauma.Selected for this study were 50 DTS images(DTS group),50 CT images(CT group) and 50 DR images(DR group).The image diagnoses for the 3 groups were conducted by 2 senior radiologists and their judgments were compared with the definite clinical diagnoses.The 3 groups were compared in terms of diagnostic accuracy,diagnostic rate of acute atlantoaxial trauma,image quality and effective radiation dosage.Results DR was insignificantly different from DTS or CT in diagnostic accuracy for the acute atlantoaxial Irauma which had been caused by mild violence like spraining and falling(P>0.05),but significantly inferior to both DTS and CT in diagnostic accuracy and diagnostic rate of the acute atlantoaxial trauma which had been caused by severe violence like traffic accident(P<0.05).In detection of atlas/axial fracture and atlantoaxial dislocation,DTS was slightly weaker than CT but significantly better than DR(P<0.05).The image quality scores for CT group(4.60±0.11) and DTS group(4.16±0.15) were significantly higher than that for DR group(2.80±0.18)(P<0.05).In average effective radiation dosage,CT group(2.33±0.020 mSv/time) was the highest,followed by DTS group(0.61±0.076 mSv/time) and DR group(0.025±0.003 mSv/time),showing significant differences between any two(P<0.05).Conclusions DR technique may be used for inspection of the atlantoaxial acute trauma caused by mild violence like spraining and falling,but has little value for inspection of most cases of atlantoaxial acute trauma.DTS technique may be the first choice for inspection of most atlantoaxial acute trauma.CT should be applied as a further inspection for complex cases because of its highest diagnostic accuracy and highest effective radiation dosage.

OBJECTIVE:To construct a high-efficiency, high-performance, low-cost flow of drug purchasing. METHODS: The defects involved in the current drug purchasing flowsheet prevalent in many hospitals were analyzed and the optimized flowsheet was put into practice by combining the actuality of our hospital. RESULTS & CONCLUSIONS: The traditional drug purchasing modality can not meet the requirement of current hospitals in that it involves large work load and high probability of error, and it is tedious and time-consuming. The establishment of drug catalog database and the online drug purchase by means of instant communication software can help simplify drug purchase flow, lessen work load, enhance work efficiency, and effectuate a high-efficiency, high-performance, low-cost flow of drug purchasing.

OBJECTIVE: To provide references for the practice of the zero inventory management mode in hospital drug supply storeroom.METHODS: The zero inventory management mode in hospital drug supply storeroom was summarized based on experiences of hospital drug supply storeroom management in our hospital.RESULTS & CONCLUSIONS: After introduction of zero inventory management principle in hospital drug supply storeroom,the drug turnover frequency in our hospital reached 8~9 times every quarter,which has greatly lowered drug storage costs,activated the working capital,and brought down the proportion of drug fund to as low as about 15% of total hospital working capital.Therefore,establishing a reasonable managing mode suitable to hospital condition and applying zero inventory principle in the management of hospital drug supply storeroom are of importance for lowering hospital running cots and enhancing working efficiency.
